i'iliaims. This invention relates to textile disintegrating machinesand, more particularly, to a textile dis integrating machine fordisintegrating textile waste and scrap in a manner to produce lint oflong staple fiber.

' An obj ectoi the present invention is to provide a textiledisintegrating machine which will tease out the fibers of scrap cloth,yarns, cards, and other fibrous material and produce a lint, the fibersof which are unbroken by the disintegrating operation and have a longstaple quality, in such a manner that the lint is free ofundisintegrated pieces of material.

Another object of this invention is to provide a textiledlsintegrating'machine which will draw out or parallel the fibers ofscrap cloth and other fibrous material in such a manner that the fibersthusly tease-2i out will be free from innate and in condition for laterspinning;

A further object of this invention is to provide a textiledisintegrating machine having a teasing element possessing acomparatively long life, which will thoroughly disintegrate fibrousmaterial.

. Another object of this invention is to provide a textiledisintegrating machine which may be adjusted to accommodate fibrousmaterial of various thicknesses, classes and types, so that a lint will'be obtained therefrom, which lint will have fibers oi along staplequality, unbroken by the disintegrating action of the maclune.

A still furtherobiect of the invention is to provide a teasing roll ofnovel construction for a disintegrating machine.

ther objects of the invention will become apparent in the course of thefollowing specification.

The above and other objects of this invention are accomplished byproviding a textile dosintegrating machine having a frame with a teasingroll comprising side members fixed upon a shaft rotatably mounted insaid frame, a plurality oi carrying rods extending between said sidemembers and dlsposedin an annular row about the axis of saidrolladjacent the peripheryof said side members, teasing elements comprisinga, plurality of pins of a rigid material pivotally mounted in groups inlongitudinal extension on said carrying rods, the free ends of said pinsprojecting outwardly, annular spacer plates longitudi- 'nally spacedbetween-saidside members, said spacer plates being mounted adjacentthep'e riphery thereof on alternate carrying rods and recessed therebetweento separate the pins on said alternate rods only into groups, bed platesadjacent the periphery of said'roll havingprojections thereon, extendingtoward said roll, said plates being adjustably mounted in said frame tomove said projections toward and away from said roll, and means adjacentthe surface of said roli for feeding the material to be disintegratedinto contact with said teasing elements.

The invention will appear more clearly from the following detaileddescription when taken in connection with the accompanying drawings,showing by way of example a preferred embodi-= ment oi? the invention.

Figure 8 is an eievational view of said modified picker pin;

Referring to Figure 1' of thedrawings, the side ,frame of the machine isdesignated by the reference numeral it. The side frameit' has anextension i ion one end thereof, saidextension having rotatably mountedthereon transversely," extending longitudinally spaced rollers l2 and itover which passesanendless apron iksaid rollers being driven from anysuitable source of power. Joumaled in bearings l5, on-the side framesIt, is a mainshaft' it having mounted for rotation therewitha. noveltype of teasing roll l1 herein-' posed of opposite side members l6 andI9 fixed upon the shaft 16, preferably by means of keys 20. The sidemembers l6 and I9 are held in spaced relation to one another by means ofspacer rods 2|, having a plurality of sleeves 22 positioned thereon. Theends of the spacer rods 2| are screw-threaded to receive nuts 23, sothat the side members may be removed from the spacer bars, if sodesired. A. covering plate 24 is provided to cover the side member l8,while a covering plate 25 is providedto likewise cover the side memberl9.

Mounted in the side members l8 and IS in inwardly spaced relation to theperiphery of the same is a plurality of carrying rods 26 which extendbetween the side members and are disposed in an annular row abo t theaxis of the roll l1. Pivotally mounted on the carrying rods 26 is aplurality of picker pins 2'! which extend longitudinally between theside members l6 and IS.

The picker pins 21 are of a rigid material, each having a shank 28.pointed at its outer end, which end projects beyond the periphery of theside members. The inner end of the shank 28 has formed thereon an eye 29adapted to movably fit on the carrying rods 26. In this manner, thepicker pins 21 may swing or pivot on the carrying rods, as shown in dotand dash lines in Figure 3A of the drawings. The shank 28 preferablyextends from the central portion of the eye 29, as

shown in Figure 3A of the drawings. However, the shank 28 may be offsetin respect to the eye 29, as shown in Figure 4 of the drawings.

When the machine is used for disintegrating a thick material. such as.for example. carpet,

which mater al offers a reat resistance to the picker pins 21, stop rods30 are used to limit the pivotal movement of the pins 21. The stop rods30 are mounted in and extend between the side members l8 and IS. Thestop rods are positioned so as to be located between each r w of pickerpins and be engaged by the shanks 26 thereof thereby limiting thepivotal or oscillating movement of the pins.

The stop rods 36 are not necessary when a thin material offering littleresistance, such as silk, is being disintegrated. The centrifugal forcecaused by rotation of the teasing roll I! acts to prevent the pickerpins from pivoting too great a distance away from the. cloth and insuressufficient contact between the points of the picker pins 21 and thecloth.

Stop rods may be eliminated even when it is desired to disintegrate athick material, such as carpeting, by the use of a modified form ofpicker pin 21, as illutrated in Figures 5 to 8, inclusive, of thedrawings. The modified form of picker pin has an angular-shaped shank 3|pointed at the top thereof. The picker pin is made of a rigid material,preferably of sheet metal, and is not flexible and will not bend.Adjacent the opposite end of the pin is an aperture 32 of suflicientsize to accommodate one of the carrying rods 26, so that the picker pinmay be mounted on and have pivotal movement in respect to said rod. Thebase of the picker pin has projections 33 and 34 formed on oppositesides thereof. The projections are of suflicient length to engage anadjacent carrying rod when the picker pin pivots or reciprocates on thecarrying rod 26 upon which it is mounted, which limits the pivotal, orreciprocating, movement of the pivot pin.

.As shown in Figure 6 of the drawings in dot and dash lines, when thepicker pin 21 swings to the right, the extension 34 engages the carryingrod 26a, which limits the pivotal movement of the picker pin to'theright. Should the picker pin 21 swing to the left, the extension 33 willengage the carrying rod 26b, limiting the movement of the picker pin tothe left. The pivotal, or swinging, movement of the pins may be governedby the length of the extensions 33 and 34. The picker pins2l are placedupon the carrying rods in staggered relation to one another, so that theextensions on a picker pin mounted on one of the carrying rods 26 willmove between the extensions on the picker pins mounted on the adjacentcarrying rods. For example, the picker pin is placed on carrying rods26a and 26b. Another picker pin is then mounted on the carrying rod 26between the rods 26a and 261). Further picker pins would then be placedon the carrying rods 26b and then another picker pin placed on the rod,26:: and so until rows of picker pins extend across the machine.

Both forms of picker pins are held against lateral movement and dividedinto groups on the carrying rod 26 by means of spacer plates 33. Thespacer plates 35 are annular in shape and are held against lateralmovement on the spacer rods 2| by means of sleeves 22 on the rods 2|.

Inwardly of the periphery of said spacer plates the spacer platesextending upwardly of the carrying rods a sufllcient distance to bearagainst the shank of the picker pins. The periphery of the spacer platesbetween the apertures 36 is recessed at 31, as shown more particularlyin Figure 3 of the drawings, 30 as to avoid engaging'with the carryingrods and picker pins intermediate of the apertures 36. The adjacentspacer plate 35, which is similar to the first-mentioned spacer plate,is so positioned that the apertures 36 therein will engage theintermediate carrying rods 26, which rods were not engaged by theapertures in the first-mentioned spacerplate.

In this manner, the picker pins on each carrying rod are divided into aplurality of groups by the spacer plates. However, the groups are sodivided that the space between them formed by the spacer plate will beara staggered relation'to the space between the groupsof picker pins onthe adjacent carrying rods. In this manner, the entire width of theteasing roll I1 is covered by the picker pins and is effective todisintegrate the material. No ribbons or pieces are formed in thematerial being disintegrated as the spaces between the groups of pickerpins on one carrying rod is followed by picker pins'on the nextsucceeding carrying rod.

Mounted adjacent the periphery of the teasing roll II at the bottomthereof in an are concentric to said teasing roll and in radialalignment with the axis of the teasing roll is a plurality 39 hasslide-ways 4| therein, the frame it having similar slide-ways 42adjacent the slide-ways 4|. Extending through theslide-ways 40 and 4|and into the bed'plate 38 are bolts 43 and 44. The bracket 39 has anextension 45 on the bottom thereof in which is positioned a set screw 46having a head thereon so that the bed plates may be assneas the apron i4and is moved toward the feed rollers 50 and BI and passes therethrough.From the feed rollers 50 and II the'material passes moved toward theteasing roll H or drawn away therefrom by turning the set screws inopposite directions. When the bolts 43 and 44 are loosened, the bedplate 38 may be moved towardor away from the teasing roll II by turningthe set screw 48. The setting may be maintained by tightening the bolts43 and 44. Onthe face 41 of the bed plate 38, which face conforms to thesurface of the roll I1, is positioned a plurality of pointed projections48. In the embodiment of the bed plate shown in Figure 9 of thedrawings, these projections comprise a plurality of pins positionedwithin the face of the bed plate. In the modified bed plate shown inFigure 10, the projections comprise pointed serrations 49 formed in theface 41 of the bed plate 38.

Located intermediate the inner end of the apron i 4 and thedisintegrating, or teasin roll I! is a mechanism for feeding to thedisintegrating roll the material to be disintegrated. This mechanismcomprises a pair of transversely extending feed rollers 50 and iii, theroller 50 being positioned above the roller 5|. Intermediate of the feedrollers 50 and El and the periphery of the teasing roll H, and closelyadjacent thereto, is a' pair of gripper rollers 52 and 53, a guide plate54 being positioned between the roller 53 and the disintegrating roll H.The rollers 5i and 53 may b driven by means of a belt or chain drive 55,so that the material placed on the apron 14 will be moved intoengagement with the feed rollers 50 and SI and thence through thegripper rollers 52 and 53 and over the guide plate 54 into contact withthe picker pins on the disintegrating roll II. If so desired, a ring 56may be positioned about the peripheries of each of the side members l8and I9, said rings 56 having pointed picker pins 5! mounted in the outersurface thereon. In this manner, the full width of the teasing roll I Imay be utilized for disintegratingmateriaL In the operation of thetextil disintegrating machine of this invention, power is applied to theteasing roll ll through the belt Ila and the shaft I6, as shown inFigure 1 of the drawings, the roll I! being rotated at a higher rate ofspeed than the feeding mechanism. Byway of example, the teasing-roll I7is rotated in a counter-clockwise direction. Since the picker pins 2'?are pivotally mounted onthe carrying rods 26, the picker pins tend toswing radially outwardly through centrifugal force whenthe teasing rollI! is rotated'rapidly. At thesame time, power is applied to the rollersi2 and is, rotating the same at a slower speed than the roll H, forexample, in a clockwise direction, as shown in Figure 1 of the drawings.

The source of power for rotating the rollers may be the same as thesource of power for rotating the teasing roll H, or independent sourceof power may be used. The rollers 5i and 53 are also rotated in aclockwise direction, the roller 5i being connected by a drive chain, orbelt, to the roller 12, and the roller 53 likewise being connected tothe roller 5! through another belt a clockwise direction will rotate theidling rollers 52 and so in a counter-clockwise direction.

The material to be disintegrated is placed upon through the gripperrollers 52 and 53 and thence over the guide plate 54. The material isthen engaged by the picker pins 21. 7

Since the picker pins 21, which are rigid and will not bend, arepivotally mounted on the carrying rods 28, centrifugal force caused bythe rapid rotation of the teasing roll 11 will cause the picker pins toextend radially from the teasing roll until the same enga e the materialto be disintegrated. Upon engaging the material to be disintegrated, theresistance of the material causes the picker pins 21 to yield slightlyagainst the centrifugal force created by rotation of the roll II, as thepins are dragged over one side of the material. For example, when theteasing roller is being rotated in a counter-clockwise direction, asillustrated in-Figure 1, the

- picker pins upon contacting the material will or carding action issecured, the fibers being pivot on the carrying rods 26 in a clockwisedirection due to the resistance of the material. In other words, thepicker pins 21 exert only enough force on the cloth to draw or tease outthe fibers. An excess force sufllclent to break or tear the fibers isprevented since the pins may pivot away from the material, yet,centrifugal force insures 'a suficient contact between the pins and thematerial to properlydraw out the fibers.

The opposite side of the material is engaged by the projections 49 orpins- 48 on the bed plates 38. As the material is engaged by the pickerpins 27, it is moved over the pins 48. The pins 48 tend to hold thematerial against movement by the picker pins 21. In this manner, agarnett drawn or paralleled from the material without knots or snagsWhen a thick material offering a high resistance to the picker pins isto be disintegrated,

ful

the stop rods 80 are inserted in the machine and the'pivotal movement ofthe pins 21 is limited by contact with the rods. In other words, whenthe resistance offered by the material is in excess to that of thecentrifugal force created by rotation of the teasing roll II, it isnecessary to limit the pivotal movement of the pins so that the pin willbe held in proper engagement with the material as they pass thereover.

The bed plates 38 are adjustable toward or away from the teasing roll,so that material of various thicknesses may be accommodated by themachine and so that any wear of the picker pins may be compensated for.The material is moved by this action to the right of Figure 1 a it isdisintegrated. The projection 48 also engage the fibersand assist in thedisintegration of the material, a lint of long stable fiber resulting.

The lint or fibers pass from the machine on :or chain. Rotation of therollers 5| and 53 in ing roll it of this invention the lint from thedisintegrated material is of uniform quality, there being no widestrips, or ribbons, of material, since by staggering thegroups of pickerpins on the various carrying rods 26 the entire surface of any materialin the machine is engaged by picker pins, as the teasing roll isrotated. The fibers are also of long stable quality and free from knotsand snags.

With the form of picker pin 21 having an offset shank 28, as illustratedin Figure 3 of the drawings, as the teasing roll I! is rotated. the'pins, because the shank is offset in respect to the eye The teasing rolli1. is constructed in such a manner that it is easily assembled, itbeing merely necessary to position the side members l8 and I9 upon theshaft IS, the spacer plates 35 being positioned between the side membersin spaced relation to one another. The spacer rods 2|, having sleevespositioned thereon between the plates 35, are anchored in the oppositeside members l8 and is, the side members and spacer plates being firmlyheld in spaced relation to one another by drawing the nuts on the endsof the spacer rods tightly against the side members, the sleeves betweenthe spacer plates holding the same against lateral movement. Alternatespacer plates 35 are so positioned in relation to one another that theapertures 36 therein will engage alternate carrying rods 28. Theapertures 36 of the intermediate spacer plates are positioned to engagethe intermediate carrying rods 26. The carrying rods are then insertedthrough a side member, a group of picker pins 21 being slided thereonprior to the carrying rods passing through the spacer plates 35, whichplates separate the group of picker pins. If stop rods 30 are to be usedthey are positioned in the side members l8 and I8 and between the rowsof picker pins.

The cover plate 24 may then be fastened by means of screws 59 to theside member I8 and the covering plate 25 likewise applied over the sidemember IS.

The modified form of picker pin, as shown in Figures 5 to 8, inclusive,are in their operation the same as the preferred embodiment of thepicker pin, as shown in Figures 1 to 4, except that the stop rods arenot necessary. The projections 34 and 33 on the base of the picker pinswill engage the carrying rods 28 on opposite sides of the carrying rodupon which the picker pin is mounted and limit the pivotal movement ofthe pins.

In all forms of the picker pins of this invention, the pins 21 are madeof rigid material, so that the same will not become bent, as, forexample, will occur when a flexible picker pin or brush is used. A rigidpin likewise would not lose its shape, such as would happen when a brushor bristle is used and will not quickly become worn, nor will the rigidpins become matted or clogged with lint and fibers as will a brush.

The rigid pins will not tear or break the fiber of the material, sincethe same are pivotally mounted on the carrying rods 26 and since the bedplates 38 may be adjusted toward or away from the teasing roller II toaccommodate the thickness and type of material to be disintegrated inthe machine, the bed plate being adjusted in an are which is concentricto the teasing roll II.

It is apparent that the specific illustrations shown have been given byway of illustration and not by way of limitation and that the structureabove described is subject to a wide variation and modification withoutdeparting from the scope or intent of the invention, all of whichvariations and modifications are to be included within the scope of thepresent invention.
